| 摘 要： | 小沟里金矿床属石英脉型金矿 ,产于西秦岭泥盆系中统碎屑岩中 ,矿床规模已达中型。蚀变以硅化、钠长石化、毒砂化、黄铁矿化、绢云母化为特征 ,矿石中金以自然金为主 ,石英、钠长石、方解石和白云石是主要载金矿物。裂隙构造是矿床最主要的控矿因素。

| Abstract: | Xiaogouli gold deoposit is quartz-vein type gold deposit.It is hosted in the clastic rock of Middle Devonian series in West Qinling area.The gold deposit has already reached a medium-sized deposit with mining progress.Thermal alterations feathure is mainly as following:silicification,albitization,sericitization,arsenopyrite and pyritization.Native gold is the dominat gold mineral in ore.Quartz,albite,calcite,dolomite are main gold carriers.Fractures act as the most important ore-controlling factor. |
